Surgery was performed using aseptic procedures. Anaesthesia was induced using ketamine, which was followed by 2 C5% isofluorane Tolbutamide mixed with oxygen administered by inhalation for the length of the surgical procedure. The skin and fascia were removed from the dorsal surface of the skull. At 10 points around the circumference of the head, stainless steel screws were screwed into the skull and connected together with a wire; the screw heads and the wire were then inserted into a plastic cast to form a circular base. Later,while searching for neurons before Triciribine behavioural tests, awake cats were rigidly held by this base. The base was also used for fixation of connectors, a miniature micro drive, preamplifiers, contacts for stimulating electrodes, and a protective and electrically shielding cap. A portion of the skull and dura above the left motor cortex, over approximately 0.6 cm2, were removed. The area of the motor cortex was visually identified by the surface features and photographed. The aperture was then covered by a plastic plate 1mm thick, in which approximately 100 holes (0.36mm in diameter) had been drilled and filled by sterile wax. The plate was fastened to the Valproic acid surrounding bone by orthodontic resin (Densply Caulk).
Two 26-gauge hypodermic guide tubes were implanted vertically above the medullar pyramid at the Horsley and Clarke coordinates (P 10, L 0.5) and (P 10, L 1.5), at the depth of H 0 for insertion of U0126 stimulating electrodes into the pyramidal tract later in the awake state. Following the surgery, the cat was placed in a warm padded cage and respiration and reflexes were monitored until it regained conscious. Analgesic enrofloxacin (Baytril, purchased from Bayer; 2.5?C5.0 mg kg?1) was administered intramuscularly on the day of surgery and two times a day for five to seven subsequent days. Triple antibiotic ointment bacitracin Cneomycin?Cpolymyxin was applied daily to wounds margins around the head implant for the duration of experiments. After several days of recovery, experiments were initiated by placing the animal in the head-restraining device. The cat was positioned on a table equipped with a foam rubber pad, encouraged to take a sphinx position, and allowed to rest for several minutes. Then the base attached to the skull during surgery was fastened to the restraining device so that the resting position of the cat s head was Varespladib approximated. This procedure minimized stress on the neck while the head was temporarily immobilized and the body was put in a comfortable position. Over several days, a number of sessions of increasing duration were used to accustom the cat to the head restrainer. After several training sessions, all cats sat quietly with their head restrained. They did not seem to be disturbed by the restrainer because they frequently fell asleep. Then neuronal recordings were initiated.
